German cockroaches are small (about 12 to 15 mm), light brown with two dark stripes behind the head, and live indoors in kitchens and appliances. American cockroaches are much bigger (around 35 to 40 mm), reddish-brown, and live in drains, sewers and roof spaces. German cockroaches breed far faster and usually need a more intensive treatment.
How to identify a German cockroach

- Light tan to brown with two dark parallel stripes behind the head
- Found in kitchens, fridge motors, microwaves, cupboard hinges and bathrooms

How to identify an American cockroach
- Large: around 35 to 40 mm long

Why does the type of cockroach matter?
German cockroaches live and breed entirely indoors and multiply very quickly, so the treatment focuses on gel baiting inside kitchens and appliances, with a follow-up to catch hatching nymphs. American cockroaches are mostly coming in from outside, so treatment targets drains, manholes, roof spaces and entry points, along with sealing gaps.
Which cockroach is more common in Cape Town?
Both are common. German cockroaches dominate in flats, restaurants and busy kitchens, while American cockroaches are often seen in houses near drains and in older buildings. Sending a clear photo on WhatsApp is the quickest way to find out which one you have.
Frequently asked questions
Can German cockroaches fly?
German cockroaches have wings but rarely fly. American cockroaches can glide or fly short distances, especially in warm weather.
Are German cockroaches harder to get rid of?
Yes. They breed much faster and hide inside appliances and cupboards, so they usually need targeted gel baiting and a follow-up treatment.
Do American cockroaches mean my house is dirty?
Not necessarily. American cockroaches often come in from drains and sewers regardless of how clean a home is.
